12-12. What is the primary fire-fighting agent used to extinguish burning flammable or combustible liquid spill fires? 1. Water 2. AFFF 3. PKP 4. Halon 12-13. By what means does CO2  extinguish a fire? 1. By cooling the fire below its ignition temperature 2. By eliminating all heat 3. By diluting and displacing its oxygen supply 4. By settling and blanketing the fire 12-14. By what means does Halon 1211 extinguish a fire? 1. By cooling the fire below its ignition temperature 2. By eliminating all heat 3. By settling and blanketing the fire 4. By inhibiting the chemical chain reaction and decomposing upon contact with flames 12-15. What two fire-fighting agents are used in the twin agent units on board flight and hangar deck mobile fire-fighting equipment? 1. AFFF/Halon 1211 2. CO2/PKP 3. Water/AFFF 4. PKP/Halon 1211 12-16. What fire-fighting agent is used for combating flammable liquid fires? 1. Water fog 2. AFFF 3. PKP 4. CO2 12-17. What is the diameter of fire hoses used on board naval ships? 1. 1/2 or 1 inch 2. 1 1/2 or 2 1/2 inch 3. 2 or 3 inch 4. 2 1/2 or 3 1/2 inch 12-18. How many gallons of concentrated AFFF are contained in a high-capacity AFFF station on board ship? 1. 200 gallons 2. 400 gallons 3. 600 gallons 4. 800 gallons 12-19. Where are the AFFF sprinkler systems installed in the hangar bay aboard ship? 1. In the overhead 2. On the hangar deck 3. On each bulkhead 4. In each CONFLAG station 12-20. Where  are  the  flight  deck  AFFF  fixed fire-fighting system controls located? 1. Primary flight control (Pri-Fly) 2. Navigation bridge 3. Both 1 and 2 above 4. Flight deck control 12-21. Vari-nozzles are used on all AFFF and saltwater hose lines. All nozzle gallon- per-minute flow rates are based on what psi pressure at the nozzle inlet? 1. 100 psi pressure 2. 200 psi pressure 3. 300 psi pressure 4. 400 psi pressure 12-22. What is (a) the length of Navy fire hoses and (b) the maximum operating pressure? 1. (a) 20 feet (b) 100 psi 2. (a) 35 feet (b) 225 psi 3. (a) 50 feet (b) 270 psi 4. (a) 75 feet (b) 340 psi 12-23. Fire hose pressure above 150 psi is hazardous because excessive nozzle reaction force may result in loss of nozzle control. 1. True 2. False 12-24. What is the purpose of the hard-rubber and hardwood plugs contained in the aircraft tool kit? 1. To seal ruptured fire hoses 2. To stop fuel tank leaks 3. To seal off aircraft intakes 4. To wedge open aircraft canopies 12-25. How  does  aluminized  protective  clothing provide protection to fire fighters? 1. Because of its thermal lining 2. Because of a positive airflow valve that cools the wearer 3. Due to its high percentage of reflectivity to radiant heat 4. Because of its lightweight fabric con- struction and ease of mobility 12-24
